Recommendations on very colorful fish?
I keep and breed shrimp and often have culls that I would feel better about putting back into the chain of life.
My wife is up for the idea of a display tank with fish, but
1) the fish have to be extremely colorful
2) be peaceful enough to be kept with several of it's colorful kind (that leaves bettas out)
3) kept in a 10g or 20g long
Ideas or suggestions would definitely be welcome!
